D6500 would probably work for you, but you would want to double check the fitment to make sure it will work with your application.

Does this have the 3800 Series II Supercharged motor? If it does then it probably has the same fitment dimensions as my 2004 Impala SS. What battery would work for me up front and what would you recommend as a rear battery for me. I am running a 1500d at full tilt with a 240amp alternator (135@idle),0awg Big 3,Yellowtop up front and a volt booster sitting @14.9v-15v..But when im sitting at a light jamming to some lows that are constant and never give my system to recharge, would keeping the yellowtop up front since its fairly new and just throwing a XS battery big enough to keep my volts up for at least 5min at idle. How big of a battery would I need and how long could it keep the volts up at a stop before it starting to drop.I also plan on upgrading to a SAZ-2500 in the close future so going overkill on the rear battery would be better than doing just enough. Also I think putting in your D680 battery or whatever the small one would honestly be efficent enough to at least keep my volts around 13.5v but I just need something that can do that for a little longer period of time. Any suggestions? I just want the rear for now but maybe would consider swapping the front if just putting a D3400 under the hood could do the trick without even needing a 2nd battery
